High cabinet
The internal wall of the general laboratory should be provided with embedded or wall hanging cabinets (racks). The distance between the bottom of the goods cabinet (rack) and the ground shall not be less than 1.20m. The article cabinet (rack) shall have sufficient bearing capacity and shall be firmly connected with the wall. The position of the transverse partition of the article cabinet (rack) shall be movable up and down.

Experimental bench
According to the experimental needs, the working bench can be made of steel or wood. In order to facilitate the experiment and save space, a round stool is usually used. If the round stool is made of steel, the height can also be adjusted. The instrument laboratory can use the back chair with pulley for easy operation.
(V) special cart for laboratory
The special container truck for the laboratory improves the safety and convenience of the storage of articles, and also makes the experimental operation more convenient and efficient.
The laboratory shall be provided with safety stations and emergency devices as required, such as eye washer, shower, fire extinguisher, protective gloves, protective clothing, absorbent materials, etc. The best location for the safety station is the main entrance of the laboratory, which is convenient for staff to use and maintain. If necessary, multiple safety stations shall be considered for use by staff.
Clean cabinet
Clean cabinet, also known as ultra clean workbench, is widely used in biology, medicine, health, electronics, precision instruments, meters and other industries. It can provide a sterile and dust-free clean operating environment.
Biosafety cabinet
Biosafety cabinets are divided into three levels:
Level I: equivalent to the function of the detoxification cabinet with filter, to protect the operator and the environment;
Level II: simultaneously protect the operator, environment and samples, applicable to biosafety level 1 / 2 / 3 samples;
Level III: simultaneously protect the operator, the environment and the sample. The operating environment is completely isolated from the external environment. It is equipped with a glove box and is fully closed. It is suitable for the experimental operation of high-risk samples.
Exhaust hood
At present, the laboratory has basically eliminated the old smoke exhaust hood that can only rotate horizontally and translate vertically, and used the universal smoke exhaust hood that can rotate freely. There are three types of universal smoke exhaust hood, namely, hanging on the ceiling, installing on the wall and installing on the desktop.
The laboratory shall have a certain number of ventilation times to ensure that the indoor volatile and harmful substances are discharged out of the room in time. The ventilation times are related to the number of ventilators and the air exchange rate of each ventilator. Generally, the ventilation times are 5 times / H-6 times / h when the laboratory is empty.
Sky platform
Most of the scales commonly used in the laboratory are desktop scales. The analytical balance can be set on a stable fixed anti vibration workbench. The platform of high-precision mechanical analytical balance has high requirements for anti vibration.
Special instrument platform
The workbench used for placing instruments and equipment is generally required to be stable and firm, with load-bearing requirements or thermal insulation requirements. Commercially available worktables are made of steel, with high-grade decorative plates and stainless steel countertops. They can bear 300kg, 500kg and 800kg. They can be selected as long as they meet functional requirements.
Laboratory supporting equipment
1. Drip rack
Test tubes and other experimental utensils can be stored after drying on the drip rack after cleaning.
2. Sink and faucet
(1) Sink
In addition to meeting the special requirements of laboratory supplies and materials, such as acid, alkali and corrosion resistance, the water tank for laboratory shall be easy to clean, install and replace. The water tank for the experiment is divided into one-piece molding, that is, it is pressed and molded with the panel of the experimental platform at the same time during production, and it is characterized by seamless and easy to clean. The other one is assembled after being separated from the test bench. There is a gap, and the waste liquid is easy to penetrate into the gap. The production materials include PP plastics, ceramics, cement and epoxy resin.
(2) Faucet
According to the special needs of the laboratory, the gas faucet and faucet shall be equipped. The requirements are: solid and durable, easy to connect the gas pipe and the water pipe. Therefore, the faucet mouth is different from the traditional faucet, such as the embryonic faucet, and anti-skid treatment. The faucet can be single (or called single port), double, triple and quadruple, and the material can be steel or copper.
(3) Shower equipment
When an accident occurs during the experiment and the laboratory personnel are splashed with chemicals, the laboratory flushing equipment shall be used for preliminary emergency treatment to protect the safety of the laboratory personnel.
(4) Hardware
Hardware of laboratory furniture, such as drawer slide rail, handle and door hinge, ensures the reliability and durability of laboratory
